  • Cellular Respiration and Photosynthesis

  • Cellular RespirationCellular Respiration: The breakdown of food (glucose) for energy

    Takes place in all organisms: a. Plants b. Animals c. Bacteria d. One-celled paramecium and amoeba.

    A process that occurs continuously in all organisms.

  • Useable EnergyATP: energy used at the cellular levelmitosis 2. protein production3. active transport

    ATP is also used by the body4. movement 5. breathing 6. thinkingetc

  • Useable Energy ATP is made in two ways:

    Aerobic Cellular Respiration: if oxygen is used

    Anaerobic Cellular Respiration: if oxygen is not used

  • ATP Also known as Adenosine Triphosphate. It contains: Adenine - contains nitrogen A sugar called ribose 3 phosphates with 2 high energy phosphate bonds

  • Recycled ATPRemoving A Phosphate Group From ATP Releases Energy & forms ADP

    Adding A Phosphate Group To ADP stores Energy in ATP

  • AEROBIC CELLULAR RESPIRATION Takes place in the mitochondria of plants and animals

    Oxygen is necessary

    SUMMARY EQUATION: C6H12O6 + O12 6H2O + 6CO2 + 36 ATP glucose + oxygen water + carbon dioxide + 36 ATP

  • 3 Steps - AEROBIC RESPIRATION Glycolysis

    Krebs Cycle

    Electron Transport Chain

  • Aerobic respiration Step 1 is called GlycolysisKrebscycleGlucoseGlycolysis in theCytoplasmPyruvatePyruvateElectron Transport Chain

  • ANAEROBIC RESPIRATION FERMENTATION: - also known as anaerobic respirationCarried out where oxygen is lackingStill uses glucose as fuel

    Two types:Lactic Acid Fermentation:Makes 2 ATPAssociated with muscle fatigue

    Ethyl Alcohol Fermentation:Makes 2 ATPImportant to the brewing and baking industries

  • PhotosynthesisPhotosynthesis: process where plants use sunlight to make (glucose)

    The energy for life comes from the Sun

  • Photosynthesis SUMMARY EQUATION:

    6CO2 + 6H2O + C6H12O6 + 6O2Carbon dioxide + water + sunlight glucose + oxygen

  • Photosynthesis - starts with light

  • PhotosynthesisChloroplasts: organelles that carry on photosynthesis

    Follow the suns path.

    1. Suns rays hits a leaf 2. Enters into a plant cell 3. Enters into a chloroplast 4. Enters into thylakoid membrane (where photosynthesis takes place)

  • Where in the Chloroplasts doesPhotosynthesis occur?

    Thylakoid membrane

  • They need one another(glucose)

  • Also during PhotosynthesisPhotolysis - the process where sunlight splits water this. H2O + sunlight H + O + electrons The Oxygen from photolysis is the air we breathe
